The library called json-server allows you to quickly run a REST API server from just a small JSON file. Which can be really useful when your building something new or trying out a frontend project.
You can make this JSON file by hand of course. But it would get tedious when your schema grows with time.
So, how can we automate the generation of this JSON file?
Here's what you need to do:
1- Install the generator
- Using npm
npm install prisma-json-server-generator
- Using yarn:
yarn add prisma-json-server-generator
2- Add the generator to your Prisma schema
generator json_server {
provider = "prisma-json-server-generator"
outputFileName = "db.json"
}
3- Run npx prisma generate for your schema(or the example below)
model User {
id Int @id @default(autoincrement())
email String @unique
name String?
posts Post[]
}
model Post {
id Int @id @default(autoincrement())
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
title String
content String?
published Boolean @default(false)
viewCount Int @default(0)
author User? @relation(fields: [authorId], references: [id])
authorId Int?
}
Will generate the db.json file.
4- Install json-server
npm install -g json-server
5- Now run your server!
json-server db.json
You will see something like this:
